Zencoder, the artificial intelligence coding startup founded by serial entrepreneur Andrew Filev, announced today the public beta launch of Zentester, an AI-powered agent designed to automate end-to-end software testing. This critical but often sluggish step can delay product releases by days or weeks.

The new tool represents Zencoder’s latest attempt to distinguish itself in the increasingly crowded AI coding assistant market, where companies are racing to automate not just code generation but entire software development workflows. Unlike existing AI coding tools that focus primarily on writing code, Zentester targets the verification phase — ensuring software works as intended before it reaches customers.

“Verification is the missing link in scaling AI-driven development from experimentation to production,” said Filev in an exclusive interview with VentureBeat. The CEO, who previously founded project management company Wrike and sold it to Citrix for $2.25 billion in 2021, added: “Zentester doesn’t just generate tests—it gives developers the confidence to ship by validating that their AI-generated or human-written code does what it’s supposed to do.”

The announcement comes as the AI coding market undergoes rapid consolidation. Last month,
